`ToaZZ 'whom t may concern.'

Be it known that li, PAUL S. Lrn'rz, a citizen of the United States of America,`and a resident of Chicago, county of Cook, and

rangement of an electro-magnetic armaturel for reciprocating the blade holder on the razor head; and, to provide an improved razor of this type particularly designed to simplify the operations of cleaning, honing, attaching and removing the blade.

An illustrative embodiment of this invention is shown inl the accompanying drawings, wherein y Figure 1 is a longitudinal section taken through the center of a razor to which this invention is applied. k,

Fig. 2, is a section taken on the line 2-2 of Figure 1.

Fig. 3 isfa top plan of the same, partly broken awa for the sake of clearness, and certain of t e parts being shown in dot-ted outline.

Figs. a, 5, 6, and 7 are details in perspective of the guard-holder, guard, guard adjusting yoke, and armature, respectively.

Fig 8 is a detail showing the armature stamping as it appears before it is bent into the form shown in Fig. 7.' i

Fig. 9 is a fragmentary detail, in vertical section, of the razor head, showing the blade and carriage in position for honing the blade.

The razor herein shown comprisesl a support including a hollow handle 1, having a ead 2, on which isrecprocatingly mounted. a carriage 3., by means of which a blade 4' is secured in place and caused to traverse a lard 5 adjustably supported on the head. lectro-ma etic means 6 housed within the hollow riae 3. I I t1 eferring to the drawin andlel actuates the blade cariaaai@ 1 is in the form of a tube having one end pro- ]ectlng 1nto the head 2, 'to which it is rigidly secured, and having suitable lmurled portions 7 forming a linger grip. The head 21W is preferably formed of a metal stamping bent to the shape shown in vFigures 1 and 2,

i so as to provide a hollow casing for housing part of the carriage actuating mechanism.

ormed in the bottom of the casing 2, Ais a W central opening 8, through which the handle 1 extends and, at one side thereof, the casing is formed to provide a clip 9, in which is detaehably mounted a guard holder 10 for ladjustably supporting the guard 5. 'ffl Formed at opposite ends of the carriage 3, are upstanding ears 11, forming bearings for hingedly and reciprocatingly supporting the carriage 3.

In the particular form shown, the carriage AW 3 comprises a strip of metal doubled upon itself to form a clip 12 for detachably supportmg the blade 4, and a tubular part 13, through which extends a hinge pin v14:, rig-v idly secured to the carriage. The ends of the pin 14 project through apertures 15 in the ears 11 for .swingablyy sup orting the carriage 3. The carriage 3 is of less width than the casing 2 so as to permit the carriage to freely reciprocate between the ears l 11. Embracing one end of the hinge pm 14 and bearing between the carriage 3 and the adjacent ear 141, is a helicalspring 16 which is arran ed to normally urge the carriage toward t e yother ear. The other endof the 90 pin 14 is arranged to coact with part of the electro-magnetic mechanism withln the casing 2, whereby said pin and carriage are urged against the action of the spring 18.

The carriage 3 is normally held in an inat swingable yto'an extended position axially of lluo the handle 1, as shown in Figure 9. The carriagle is locked in its extended position by a notc 17 for/med in one of the ears 11 shownin 'Figures 1 and 3. Formed, adja` cent the notch 17, is an inclined cam surma face 18 arranged to coact with the adjacent edge of the carriage 3 for guiding the latter into the notch. The notch 17 is of sufficient depth to permit the carriage to be reciprocated while in its extended facilitate honin -of the Tw f the form S. 0WD, the guardv comprises sition, so as to Mo of the guard 5, are lugs 22 forming pivoted pins for pivotally supporting the guard inl the holder 10.

ln the particular construction shown,l the guard holder 10 comprises a blade part 23, whichfits within the clip 9 towhich the holderis detachably secured by means of a hinge pin 24 formed on the clip for engagement with an aperture 25 in the holder.

The upper part of the clip 9 is recessed adjacent the pin 24, as shown at 26 in Figure 3, so as to permit the insertion and rremoval of the holder 10.

A suitablefinger grip 27, at the outer end of the blade part 23, facilitates insertion and removal of the holder. Projecting Vout- I es v respect to the holder 10 for varying the pofecting the po Wardly from the blade part 23 is a pair of spaced hooks 28, arranged to form guideways for the blade 4 for securing said blade vand its carriage lin position for shaving. Struck down from the holder 10 is apalr of lugs 29, spaced apart to receive the guard 5, and having apertures 30 for receiving the pivot pins l22 ofV the guard.

The guard 5 is angularly adjustable with sition of the teeth 20 relative to the cuttlng edge'of the bladefso as to suit the requirements of the user. 40

1n alge knurled collar 31, threaded on the i The means for adjustthe guard 5 includes an axially adjustupper part of the handle 1, and having a l `peripheral 'groove 32, in whichis loosely seated ayoke A33, having a U-shaped part 34 arranged to coact with the lugs 21 of the4 guard, whereby an axial adjustment of the collar 31 will eiect an angular adjustment of 'the guard. rllhe relative arrangement of the yoke 33 and guard 5 permits the guard and its holder10 to be readily removed as a unit from the razor for cleanin and again inserted into place without ai sition of the collar 31 on the handle 1. ith this construction afterthe guard has once been properly adjusted, the

user is assured of the same-'adjustment after the razor has been cleanedK and is again assembled ready for use. l

In the form shown, the electro-magnetic means 6 includes an im roved form of armal ture 35, arranged wit in the casing 2, and an electro-magnet 36 housed within the tubular handle 1. As'illustrated. the arma-' ture 35 is constructed of a metalstamping .cut to the shape shown in Figure/ 8 an to coact with one end of the carriage hln e l -pin`14v for urging the carriage against t e action of the spring 16. The amature is arranged on the upper end .of the handle l1, so that the vibration of the plate 38 through the action of the electro-magnet 36 will cause the hammer 41 -to tap against the end of the pin 14. i

`The electro-magnet 36 is in the form of a laminated soft dle of soft iron wires surrounded by the usual windings 42, and supported in insulation blocks 43 and 44. The upper end of the core ,36 projects into the casing 2 'in position tov attract the armature plate 38. Extending through the block 44, are terminals 45 for the attachment of a terminal plug, not shown.

In operation, the razor is used in the customary manner, with the guard teeth 20 engaging the face. While the blade and guard rest against the face, the collar 31 may be' adjusted to obtain anl) adjustment of the iron core preferably a bunguardA relative to the blade which will suit y the 'user'. The arrangement Jof the collar 31 on`the handle permits it to be adjusted with one finger while the razor is being drawn across the face. The movement of the blade back and forth along the results in a shearing/action of the lThe relative arrangement of the armature Ievent undue pressure is exerted on the rastationary. against the action of the spring 16. This vavoids injury to the skin whic would likely result /under such circumstances if the .armature .were positively connected to the blade carriage so as to cause vibration of the blade at all times, irrespective of thepressure applied to the razor.

Although but -one specific embodiment of this invention .has been herein shown and described, it will be understood that numerous details of the construction shown may be I altered or omitted without departix from the spirit of this invention as den by the following claims.
